Jurassic Marsh - Day 1 is the first level of Jurassic Marsh in Plants vs. Zombies 2. Primal Peashooter is pre-selected in a seed slot, and this level showcases it. When this level is finished for the first time, the player unlocks the aforementioned plant.
(Crazy Dave and Penny appear)
Penny: Alert, User Dave, My sensors indicate we have moved 153,954,765 years into the past.
Crazy Dave: Yabbers! That's before I was even born!
Penny: Correct. We seen to have landed in some form of Jurassic Marsh.
Crazy Dave: I knew I smelled more oxygen!
The player should bring one or two defensive plants. It is recommended to choose Wall-nut and Chard Guard. Combined with Primal Peashooter, these will delay zombies in the first few columns so they can be easily grouped together and taken out with instant-kills.
- The small number next to the zombie icon means that zombie will always appear in that lane, with 1 being the topmost lane and 5 being the bottommost one.

- Required plants:
Plant Sun-shrooms at the leftmost column. When the first few zombies appear, use Primal Peashooters. Keep planting until the first wave. Then, plant Snapdragons. Plant Endurians in front of the Snapdragons to protect them. If the wave contains too many zombies to handle, unleash Cherry Bomb or Grapeshot.
